The element is a shiny solid that conducts electricity and heat. The scientist is able to bend and flatten the sample when. pressure is applied to it. Based on this information, the element could NOT be a member of which group on. The average atomic mass (sometimes called atomic weight) of an element is the weighted average mass of the atoms in a naturally occurring sample of the element. Average masses are generally expressed in unified atomic mass units (u), where 1 u is equal to exactly one-twelfth the mass of a neutral atom of carbon-12 Atomic number of Carbon : 6. The atomic number of carbon atom is 6, as atomic number is the number of protons in an atom. In a carbon atom, there are 6 protons and ##6## electrons. So Atomic Number (denoted by ##Z##) for carbon atom is 6, while the atomic mass ##A## which is the sum of protons and neutrons ##n## in an atom. ##. The atomic number of carbon is 6. Its nucleus must contain: a) 6 neutrons and 6 protons. b) 3 protons and 3 neutrons. c) 6 neutrons and no electrons. d) 6 protons and no electrons. e) 6 protons and 45,073 results, page 11 Chemistry. 1) What is the atomic # for selenium? 34 2) Write the full electron configuration for selenium following the (n+l) rule? I am not sure what is meant by n+l 3.

If a carbon atom has six protons in its nucleus, its atomic number is 6. If it also has six neutrons in the nucleus, then the mass number is 6 + 6, or 12. If the atomic number of uranium is 92, then that is the number of protons in the nucleus. Because the mass number is 235, then the number of neutrons in the nucleus is 235 − 92, or 143 Electrons are much smaller in mass than protons, weighing only 9.11 × 10-28 grams, or about 1/1800 of an atomic mass unit. Therefore, they do not contribute much to an element's overall atomic mass. When considering atomic mass, it is customary to ignore the mass of any electrons and calculate the atom's mass based on the number of protons and neutrons alone. Electrons contribute greatly.

  3. Carbon, for instance, has an atomic number of 6, not because there are five elements lighter — though this is also true — but because it has six protons in its nucleus. The ordering by atomic number happens to correspond to the ordering by atomic mass, but atomic number provides a much more precise means of distinguishing elements. For one thing, atomic number is always a whole integer.
